摘要

摘要: 为明确区域积雪雪崩情况，对2024年1月喀纳斯雪崩区两条典型公路沿线积雪密度进行原位测量分析。基于中国西北大陆性气候条件下干冷积雪特征，对比自然降雪和雪崩堆积情况下的积雪密度特征，揭示积雪密度在垂直剖面上的变化规律。结果显示，不同情况下积雪密度的变化趋势具有相似性，但自然积雪的密度梯度和最大值与雪崩堆积体存在显著差异。因此，可结合积雪垂直剖面密度分布特征与最大值，提出判别雪体为自然积雪或雪崩堆积体的方法。研究成果为野外自然积雪及雪崩堆积体的分析和识别提供了科学依据。

Abstract: In order to clarify regional snow and avalanche conditions, the snow density along two typical highway lines in the Kanas avalanche area in January 2024 was measured. Based on the characteristics of dry and cold snow under the continental climate conditions of northwest China, the density of naturally deposited snow and avalanche deposition is compared. The different characteristics of the density profiles at different conditions are identified. The results show that the trends of snow density profiles under the different conditions share similarities, but the density gradient and the maximum density change significantly from naturally deposited snow to avalanche deposition. Therefore, based on the characteristics of the vertical density profile and the maximum snow density, it can be identified whether a snow deposition is from natural snowfall or an avalanche. The outcomes provide a scientific basis for the analysis and identification of natural snow and avalanche deposits in the field.
